ScienceDaily (Oct. 17, 2009) — Learning to juggle leads to changes in the white matter of the brain, an Oxford University study has shown.

The research, funded by the Wellcome Trust and Medical Research Council and published in the journal Nature Neuroscience, appears to show improved connectivity in parts of the brain involved in making movements necessary to catch the balls.

'We tend to think of the brain as being static, or even beginning to degenerate, once we reach adulthood,' says Dr Heidi Johansen-Berg of the Department of Clinical Neurology, University of Oxford, who led the work. 'In fact we find the structure of the brain is ripe for change. We've shown that it is possible for the brain to condition its own wiring system to operate more efficiently.'

Juggling is considered a good exercise to develop better right brain/left brain balance and communication. I've actually seen a very basic two-ball juggling exercise, done for just a few minutes a day, help with speech dis-fluency. I often wondered if it would also help with stuttering issues.Great article! Very interesting. Thanks for sharing!
